Do we really need 140$ Graphing calculators?

1.Do u really use ur graphing calculators?</p>

<p>2.Can a person survive college (first 2 years) without a graphing calculator?</p>

<p>3.Don't you think that using calculators instead of using pen and paper degrades ur problem solving skills?

  1. No. They didn't allow us to use them in math classes.
  2. Yes. If a person can survive the first 2~3 years of college without a booze, no graphing calcs is doable.
  3. Maybe.</p>

<p>Never had to use anything more than a scientific calculator in any class I took in undergrad (or grad so far). A TI-34 that I picked up for 10 bucks has worked out great for me.</p>

you need a ti-89 for calculus and it makes calculating stuff much more simple
for the rest, a ti83 is adequate

<p>NO!</p>

<p>Most college level calculus classes (or other math classes) do not even allow calculators. At least none of my math professors have allowed them.</p>

<p>no?
i have a ti-89 and i use it all the time in my calc bc class. It's incredibly useful for graphing slope fields, evaluating integrals, etc
No, it's not 100% necessary, but it sure makes stuff a lot easier</p>

<p>You're in high school! AP calc in high school is way different than calc in college. </p>

<p>In college you would be slapped for solving in integral with a calculator! And no one cares about the little graphs you make on your calculator; they mean nothing. Like I said most college math classes do not even allow the use of a calculator.</p>

<p>Your teacher is doing you a disservice. There is a certain amount of calculus one must be able to immediately and mechanically do to get by in some classes. Doing that stuff on a calculator will not get you to that end. My AP calc teacher would have been appalled at the thought of someone using a calculator for anything in that class.</p>

<p>rightly said, i think u require these kinda calculators only when u attain ur engineering degree and after which u start working, yea acc to my guess one would solely require a graphing calculator, when he/she starts working.
I thnk by using calcualators... to sovle integrals and stuff makes ur mind useless and makes it devoid of reasoning skills.</p>

<p>The TI-89 is ridiculous. A must have!</p>

<p>Yes if you are using a calculator to solve integrals now wait until you reach Calc3 and you are doing triple integrals and you need to solve integrals of all types without thinking about it. Also being able to visualize the integration process is very important when you transform to polar coordinates in Calc2 and spheric and cylindrical coordinates in Calc3.</p>

<p>Yeah, relying too much on graphing calculators can cripple geometric intuition, which is important for calculus III and physics.</p>

<p>They aren't even very useful for math classes--most of the time professors pick problems on homework and exams that don't require a gross amount of calculation.</p>

<p>HP-15C. 26 yrs and still going strong.</p>

<p>I don't want to hijack this thread, but I'm having a calculator crisis and am soliciting advise. After a few years of using a Palm with an HP emulator as my main calculator, I've decided that using a stylus is slowing me down way too much. I've switched to a TI-84..and it has boosted my speed back to what I want....BUT...I really miss having spreadsheets in my pocket. What I want is a calculator (with a calculator keyboard...not a QWERTY-style layout) that can also process and display standard spreadsheets. The TI-89 can "kind-of" do that...but the screen is too low-rez to really work. So...what I want is a TI-84/89 or HP-50 style calculator that has a high quality screen that can import/export spreedsheets (excel). Any suggestions?</p>

Calculators, in general, don't have large, high-resolution displays, and therefore are lousy platforms for spreadsheets. There is a free spreadsheet program for the HP-50G, known as [url=<a href="http://www.hpcalc.org/details.php?id=4936%5DXCELL%5B/url"&gt;http://www.hpcalc.org/details.php?id=4936]XCELL[/url&lt;/a&gt;], which can import Excel spreadsheets saved in TXT format. But as you can see from the screenshot, the resolution is unspectacular.</p>

<p>The new [url=<a href="http://en.wikipedia.org/wiki/Nspire%5DTI-nSpire%5B/url"&gt;http://en.wikipedia.org/wiki/Nspire]TI-nSpire[/url&lt;/a&gt;] line has a 320x240 display, probably the best for any calculator-like product. I believe it comes with a spreadsheet application, but don't know if it imports Excel files.</p>

<p>...yeah, the nSpire looks like it has minimally acceptable display resolution for spreadsheets. Unfortuntely, it looks like the excel compatibility is limited to cut-and-paste of cell values (not underlying formulas)..that's not going to work for me. Thanks for the suggestion, though. Someone needs to make a calculator with an iPhone-like display that supports spreedsheets! <hijack over=""></hijack></p>

<p>I actually have found that playing with my calculator has improved my spatial relations ability. I do jam out a lot of integrals and stuff by hand, but in a science class, the TI 89 is like, crack. Buy one, learn the special tricks for it, and you will not be able to be defeated, ever.</p>

<p>It's not going to help you in the long run. Have you ever had a teacher who could crank out mathematics at an astounding rate? I used to have a physics teacher who would throw a problem at us and stand quietly while he watched us work it out, using pencil, paper, calculator, anything. He'd stare at us quietly for about thirty seconds, giving us a head start. Then he'd look at the board. Then, one digit at a time, he would carefully write out the exact right answer to the hundredth place. We'd crank out the answer as quickly as we were able using all the tools available to us, and he would solve the whole problem in his head and calmly write the correct answer.</p>

<p>I promise you he didn't learn how to do that by messing around with his calculator.</p>

<p>Having a good working knowledge of your calculator will serve you well, but becoming reliant upon it and being convinced that it has special ability that you do not have... well, then one day your mathematical prowess is going to be felled by some dead triple A batteries.</p>

<p>That's a little freakish, I have to say. I don't think most people have the mental capacity to carry out the math entirely in their head. I, for one, can't add large numbers mentally without literally visualizing a piece of paper and a pencil in my head and doing that math like that. Maybe it's just me.</p>

I think it's possible if one starts learning kumon at his/her early age...</p>

<p>Using an advanced calculator recklessly can be dangerous, but what if you`re comfortable with the math but just want to save yourself time</p>

<p>All i think is that,it would be useful for ur brain and useful for ur reasoning and logical skills,if u use only paper and pencil for calculating for the first 2 or 3 years of college... and later when course gets advanced ,you are all ready with ur thinking arsenal...u are all ready with ur brain pumped up with reasoning and logical skills which in the long run...does help a person</p>
